Referring more in detail tothe accompany- With theabove and other objects in view ing drawings, there is illustrated a fluelcap that will become apparent as the nature of and deflector comprising a hood and a collar,

the invention is better understood, the same it being understood thatthe hood may be diconsists in the novel form, combination and rectly mounted upon the outlet flue of a gas arrangement of parts hereinafter more fully stove or range or mounted upon the upper described,-shown in the accompanying drawend of a collar, the lower end of which may ings and claimed. 1 be attached to the outlet flue of the gas stove.

In the drawings 7 Figure 1 is a bottom plan view of the hood tangular form as shown in Figures 1 and 4: of the flue cap and deflector showing the with a relatively large opening 6 therein exbottom wall thereof provided with a relatending substantially the complete width of 35 tivelylarge flanged opening for association the bottom wall and surrounded by a depend.-

The products of combustion escaping through the flue enter the hood and contacting the forwardly and upwardly inclined top wall 9 are deflected forwardly of the hood through the unobstructed front opening 10 to be directed away from the walls of the room. Air enters the hood through the slotted opening 13 and by this action increases the velocity of the products of combustion flowing through the hood to discharge them with greater force away from the walls of the room. 7

As shown in Figures 4 and 5, the forward edges of the side wall 8 are outwardly flanged as at 8a with which the rolled side edges of a grille 14 are engaged, the deflector being used either with, or without the grille. It has also been described that the slotted opening 13 is in the rear extension 12 of the bottom wall 5, but it is to be understood to be within the realm of this invention to locate the opening 13 elsewhere, such as forwardly of the opening 6, to the sides thereof, or in the side walls 8, and in fact be located wherever it will function for increasing draftthrough the deflector. As shown in F igures 6 to 8, the collar 11 is illustrated as mounted upon the flange 15 that surrounds the outlet flue of the gas range 16 and the bottom wall 5 of the hood is provided with an opening 13a at each side of the opening 6 in the bottom wall of the hood that receives the collar 11. The openings 13a are positioned at opposite sides or laterally of the opening 6 and are disposed rearwardly of the forward edge of the opening 6 as clearly shown in Figure 8, the elongated slotted opening 13 illustrated in Figures 1 to 4 being eliminated in this construction, the laterally positioned opening 13a operating to increase draft through the deflector hood, the latter otherwise being of the same construction as shown in Figures 1 to 3.

From the above detailed description of the invention it is believed that the construction and operation thereof will at once be apparent and while there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

I claim:

1. In a flue cap and deflector, a collar adapted for mounting on the outlet flue of a gas range, a deflector hood having a forward side opening therein parallel with the forward side of the outlet flue, said hood being mounted on the upper end of the collar and said hood having an air inlet opening in the bottom thereof entirely rearwardly of the forward side of the collar.

2. In a flue cap and deflector, a collar adapted for mounting on the outlet flue of a gas range, a deflector hood having a vertical forward side opening therein and mounted on the upper end of the collar, and said hood having air inlet openings in the bottom thereof in vertical planes laterally and rearwardly of the forward side of the collar.

3. In a flue cap and deflector, a hood having a forward side opening therein and adapted to be placed in communication with the outlet flue of a gas range and another opening therein laterally and entirely rearwardly of the forward edge of the flue opening for ingress of air to increase velocity of flow through the hood.

4. In a flue cap and deflector, a hood hav ing a forward side opening therein and adapted to be placed in communication with the outlet flue of a gas range and having an opening in its bottom laterally and entirely rearwardly of the forward edge of the outlet flue for ingress of air to the hood to increase the velocity of flow through the hood.

5. In a flue cap and deflector, a hood having a top deflector wall and a forward side opening, and a bottom wall, the bottom wall having an opening therein to be placed in communication with the outlet flue of a gas range and said bottom wall having another opening therein located in the bottom wall rearwardly of the forward edge of the first named opening.

6. In a flue cap and deflector, a hood having a top deflector wall and a forward side opening, and a bottom wall, the bottom wall having an opening therein to be placed in communication with the outlet flue of a gas range and said bottom wall having another opening therein for ingress of air to increase velocity of flow through the hood, said last named opening being located in the bottom wall adjacent one wall of the hood and rearwardly of the forward edge of the flue opening.

7 In a flue cap and deflector, a hood having a forward side opening therein and adapted to be placed in communication with the outlet flue of a gas range with said opening in a vertical plane parallel with the vertical side of the outlet flue and said hood having air inlet openings in the bottom laterally and rearwardly of the forward edge of the outlet flue.

8. In a flue cap and deflector, a collar adapted for mounting on the outlet flue of a gas range, a deflector hood having a forward side opening therein in a plane parallel with the forward side of the outlet flue, said hood being mounted on the upper end of the collar, and said hood having air inlet openings in the bottom thereof laterally and rearwardly of the forward side of the collar.

9. In a flue cap and deflector, a deflector hood having a forward side opening therein and adapted for mounting on the outlet flue of a gas range, and means formed within a part of the hood and located rearwardly of the forward edge of the outlet flue for in-
